The change in the way of warfare has led to a huge change in watch design, especially when the advent of aircraft, and the use of aircraft on the battlefield. In 1904, the French-Brazilian engineer Alberto Santos-Dumont, who competed with the Wright brothers for a day, asked the watchmaker Louis Cartier the need for a device that could keep the joystick in control while flying. A timepiece that can know the time, which has also become the Cartier Santos wrist watch specially designed by Louis Cartier for Santos-Dumont. Cartier Santos is unquestionably the starting point for flying timepieces. However, by today's standards, Cartier Santos is only a serious watch, and it does not have the essence of a true flying watch. It was the Germans who wanted to make a comeback from the defeat of the First World War who really realized the standard of a flying watch.
After the First World War, Germany's colonies were divided up and military equipment was highly restricted. Until Hitler came to power, he quickly violated the Treaty of Versailles and rebuilt the air force at a high speed. Before the worldwide economic depression and the vitality of the World War I countries had not recovered, the military factories of Nazi Germany had frantically built the twin-engine multi-purpose fighter He-111 under the pretext of manufacturing civil aviation transport aircraft. What followed was the need for a large number of pilots and the flying watches they wore. In the 1930s, Hitler secretly ordered the German Aviation Ministry to make a single purchase: pilot watches for mass distribution. This historical data somewhat proves that Hitler prepared the theme of mechanized warfare early on, and also allowed the German Aviation Ministry to invent and establish the specifications of the flying watch. Using the current similar products as a reference, take the Lindbergh watch of the same name produced by Longines in 1931 as an example. This watch is equipped with a flying slider that can be converted with the dial, and can calculate the required speed, altitude and distance https://www.twatchclone.ru/.
In response to the gravity environment and severe combat conditions during flight: the watch is accurate in travel time, anti-collision and anti-vibration, plus anti-magnetic; the second hand has a zero-return function, which is convenient for the crew to reduce the time difference of individual actions during combat. It is easy to read, so the diameter of the watch should not be less than 55mm. The design is for the purpose of identification at a glance. The dial is mainly dark, and the numerals are light-colored (in the future, luminous materials will be used) Arabic hour markers. The large crown makes it easy to adjust the time even when wearing gloves, and the strap is a near-modern NATO strap that can be worn directly over clothes.
However, the design obtained by the German Aviation Department did not add the flying slide rule to the design. Until the addition of the flying slide rule in the 1950s, the circular slide rule on the watch was multiplied and divided. Including conversion of average speed, distance, fuel consumption, lift rate, miles, kilometers and nautical miles.
There is also Greenwich Mean Time (GMT), and because of this system, there is the concept of time zones. Since flying can quickly pass through different time zones, this feature was added to later flying watches. Originally, the GMT time was developed to meet the requirements of pilots, so as to express the original departure time and the difference between the local time.
